Abstract
A method and device are provided for assessing the clogging risks of a well or bore hole into which a fluid is injected or pumped. According to this method controlled amounts of said fluid are caused to flow through a plurality of samples representative of the porous reservoir which are fed in parallel and whose temperature is maintained substantially constant, and the loss of permeability of said samples is measured as a function of time.
